都合があった。In the method of constructing the airtight terminal portion of the conventional storage battery, the pole pole and the annular insulating member are directly hermetically bonded to each other with brazing material, so that the pole pole expands when the brazing material is heated, and from this state it is cooled. radial contraction occurs in the pole column. As a result of this contraction, the annular insulating member connected to it receives tensile stress inward in the direction of its thickness, so the annular insulating member is often destroyed, resulting in loss of products and damage to the airtightness of the terminals. This has the disadvantage of resulting in a storage battery with deteriorated leakage resistance.

る。The present invention eliminates the above-mentioned conventional disadvantages, provides an airtight terminal portion that does not cause damage to the annular insulating member due to tensile stress, and thus provides an excellent high charge/discharge voltage performance with improved airtightness, leakage resistance, and mechanical strength. This provides a method for constructing an airtight terminal part of a storage battery, which also serves as a storage battery, and includes a pole pole that penetrates a hole in the wall of a metal container of a storage battery and has its upper end protruding outside for a terminal, and metallization on its outer periphery. In a method for constructing an airtight terminal portion of a storage battery in which a treated annular insulating member is brazed and hermetically joined to each other, the pole pillar and the annular insulating member are brazed and hermetically joined to each other via an annular metal member.

械的強度の大きい気密端子部をもつ蓄電池が得られる。Since the annular metal member is interposed between the pole pole and the annular insulating member, the pole pole and the annular insulating member facing each other can be connected to each other through the annular metal member, that is, at both side edges of the annular metal member. When brazing, the annular metal member acts as a kind of buffering and absorbing function, relieving the stress that the annular insulating member receives during brazing, so that the annular insulating member is not destroyed and, therefore, the product is protected. A storage battery having an airtight terminal portion with no loss, airtightness, leakage resistance, and high mechanical strength can be obtained.

Since the surfaces are soldered and hermetically joined to each other, the soldering work can be easily and reliably performed while observing with the naked eye, and an extremely robust soldered and hermetically sealed joint can be obtained.

の優れた蓄電池を提供することができる。On the outer periphery of the pole column 1, a 1 is formed surrounding the pole column 1 and the hole 3 thereof.
An annular insulating member 4 made of a heat-resistant inorganic material such as ceramic is interposed to electrically insulate between the pole pole 1 and the inner circumferential wall of the pole 22, and the annular insulating member 4 on the outer periphery of the pole pole 1 is For example, the annular metal members 5 having a thickness of 0.5 cm and a width of several cm are joined to each other in a sealed manner by heat welding of brazing material 6 to obtain the airtight terminal portion a of the present invention. More specifically, the annular insulating member 4 has been metallized in advance, and the inner circumferential side edge of the annular metal member 5 and the upper part of the circumferential side of the terminal pole post 1 are covered with a brazing material 6.
By heating, melting and cooling the brazing material 6, the outer peripheral side edge of the annular metal member 5 and the metallized inner peripheral surface of the annular insulating member 4 are joined together by heating, melting and cooling of the brazing material 6. The airtight terminal part a of the present invention is obtained by sealingly joining each other by so-called brazing. In this brazing operation, the pole column 1 is heated and expands in the radial direction, and then cools and contracts in the radial direction. However, in this case, according to the conventional method, the pole column and the annular insulating member are directly brazed to each other, so as the pole column contracts, the annular insulating member is soldered through the intervening joint brazing. Since the insulating member is subjected to tensile stress that is pulled inward in the radial direction, the annular ceramic insulating member, which is weak against the tensile stress in the thickness direction, is often destroyed. However, according to the present invention, as described above, the brazing materials are joined at both side edges of the annular metal member 5, so that the thermal expansion and contraction of the pole column 1 is caused by the annular metal member 5. Since the tensile stress is absorbed by the annular insulating member 4 and serves as a buffering effect on the annular insulating member 4, the tensile stress does not act on the annular insulating member 4 at all or hardly acts on the insulating member 4, and destruction of the insulating member 4 is completely prevented, resulting in good airtightness. A storage battery having a sealed terminal part a can be reliably obtained, and since it is a brazing sealing device with the annular metal member 5 interposed, the terminal part is airtight and N7R resistant! The properties and mechanical strength are significantly improved, and therefore, a storage battery particularly excellent in high charging/discharging voltage performance can be provided.

することが一般である。The annular metal member 5 is preferably made of the same material as the pole pole 1, and for example, if the pole pole 1 is made of Kovar, it is made of Kovar. The metallization treatment of the insulating member 4 is as follows:
After making the surface metallized with No-Nn etc., it is plated with nickel, and the surface and the annular metal member 5 are coated with Au-Ni.
Generally, they are brazed to each other with a brazing material 6 such as wax or AQ-Cu wax.

In this case, a stable and robust airtight battery can be obtained by obtaining the above-mentioned characteristics uniformly and in a well-balanced manner from top to bottom. The joined annular metal member is shown, and the annular insulating member 4 is shown.
The premetalized outer peripheral side surface and the inner peripheral side edge of the metallized outer peripheral side are hermetically joined to each other by brazing 9 to firmly seal the gap between the annular insulating member 4 and the cover hole surrounding wall 2, thereby forming an outer peripheral sealing part. form.

The lower part of the member 4 is fixedly supported. Although not shown in the drawings, a lead wire group of one polarity of the battery electrode plate groups is connected to the seat plate of the pole post 1.

A pair of annular metal members are interposed to seal the upper and lower end surfaces of an annular gap between the pole column and the annular insulating member, and a pair of the annular metal members are arranged to close the upper and lower end surfaces of the annular gap between the pole column and the annular insulating member. 2. The method for constructing an airtight terminal portion of a storage battery according to claim 1, wherein the upper and lower portions of the side surface and the upper and lower portions of the annular insulating member are brazed and hermetically joined to each other. 3. One of the annular metal members is interposed to seal only the upper end surface of the annular gap between the pole column and the annular insulating member, and the ring-shaped metal member is connected to the upper part of the circumferential side of the pole column through this. Claim 1, wherein the upper end portions of the annular insulating member are brazed and hermetically joined to each other.
A method of constructing an airtight terminal portion of a storage battery as described in . 4. The annular metal member has a substantially V-shaped cross section, and its outer peripheral edge is brazed and hermetically joined to a deep inclined surface that is chamfered diagonally upward to approximately the middle part of the inside of the upper part of the annular insulating member. A method of constructing an airtight terminal portion according to claim 3.
